i tried the code below, no errors, but it's also not moving rows from table sp to table sp_err

# begin fix loop

$sql = "SELECT * FROM sp WHERE NOT EXISTS (SELECT * FROM SP,SUPPLIER WHERE SUPPLIER.snum = SP.snum)";
$sth2 = $dbh->prepare($sql);
$sth2->execute or die "Error: $DBI::errstr\n";

$sth2->bind_col(1,\$spnum);
$sth2->bind_col(2,\$snum);
$sth2->bind_col(3,\$pnum);
$sth2->bind_col(4,\$qty);

while($sth->fetch){
$sql = "INSERT INTO sp_err SELECT * FROM sp WHERE spnum = $spnum && snum = $snum";
$sth = $dbh->prepare($sql);
$sth->execute or die "Error: $DBI::errstr\n";
print "deleted row";

}
